Answer:
26 miles * 5280 ft/ 1 mile
Step-by-step explanation:
We know there are 5280 ft in 1 mile
26 miles * 5280 ft/ 1 mile
Answer:
x=-8,y=-2
Step-by-step explanation:
x=2+5 y
put value of x in eq 2
9(2+5 y)+8=32 y
18+45 y+8=32 y
26=32 y-45 y
26=-13 y
y=26/-13
y=-2
put value of y in eq x=2+5 y
x=2+5(-2)
x=2-10=-8
LG = MN

Suppose the student guesses the answers, we shall consider this a binomial probability problem of success. This implies that getting a question right is p=1/5.
The number of questions is n=20 questions.
The mean of binomial distribution is
mean=n*p= 20*1/5=4
b] The standard deviation of a binomial distribution is given by:
σ=√(n*p*(1-p))
=√(20*0.2*0.8)
=1.79~1.8
Answer:
μ=4 ; σ=1.8
